载人航天器防火安全设计

防火安全是载人航天器总体设计所关注的重点项目之一。文章按照火灾发生三要素,结合以往密封舱防火安全设计经验,从密封舱内可燃物控制、舱内氧浓度控制、防止点火源形成、防止火灾传播、密封舱烟火监测和密封舱灭火6个方面对载人航天器防火安全设计方法进行了归纳总结。该研究可为我国后续载人航天器密封舱防火设计提供重要依据,确保载人航天器任务期间的安全可靠性。

Fire safety design for manned spacecraft

Fire safety is one of the most important concerns in the overall design of manned spacecrafts. Based on the engineering practice of fire safety design for manned spacecraft in our country, this paper reviews the methods for ensuring the fire safety in a sealed cabin, including the control of the three elements of fire, i.e., the combustible materials, the oxygen concentration, and the ignition source; as well as to guard against fire spreading, to implement smoke and fire monitoring, and to take timely countermeasures in case of fire. The research can provide a reference for later engineering designs to ensure the flight safety of manned spacecrafts.
